Abstract

Systems, methods, and computer-readable media for providing multi-cloud connectivity. A method can involve adding a new virtual private cloud (VPC) to a multi-cloud environment including a private network and VPCs connected to the private network via a segment routing (SR) domain and respective virtual routers on the VPCs and the private network. The method can involve deploying a new virtual router on the new VPC, registering the new virtual router at a BGP controller in the multi-cloud environment, and receiving, at the BGP controller, topology information from the new virtual router. The method can further involve identifying routes in the multi-cloud environment based on paths computed based on the topology information, sending, to the new virtual router, routing information including the routes, SR identifiers and SR policies, and based on the routing information, providing interconnectivity between the private network, the VPCs, and the new VPC.

Claims20

Dependent claims

A method comprising:

adding a new virtual private cloud to a multi-cloud environment comprising a private network and one or more virtual private clouds connected to the private network via a segment routing domain and respective virtual routers on the one or more virtual private clouds and the private network;
deploying, on the new virtual private cloud, a new virtual router configured to route incoming and outgoing traffic for the new virtual private cloud;
registering the new virtual router at a border gateway protocol (BGP) controller in the multi-cloud environment;
receiving, at the BGP controller and from the new virtual router, topology information associated with the new virtual private cloud;
identifying routes in the multi-cloud environment based on one or more paths computed based on the topology information, wherein the one or more paths are between at least one of the private network, the one or more virtual private clouds, and the new virtual private cloud on the multi-cloud environment;
sending, by the BGP controller to the new virtual router, routing information for communicating across the multi-cloud environment, the routing information comprising the routes, segment routing identifiers and segment routing policies associated with the multi-cloud environment;
and
based on the routing information, providing interconnectivity between the private network, the one or more virtual private clouds, and the new virtual private cloud on the multi-cloud environment via the segment routing domain, the respective virtual routers, and the new virtual router.

5 more elements

A system comprising:

one or more processors;
and
at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the system to:
add a new virtual private cloud to a multi-cloud environment comprising a private network associated with a cloud consumer and one or more virtual private clouds connected to the private network via a segment routing domain and respective virtual routers on the one or more virtual private clouds and the private network;
in response to adding the new virtual private cloud, deploy, on the new virtual private cloud, a new virtual router configured to route incoming and outgoing traffic for the new virtual private cloud;
receive, from the new virtual router, topology information associated with the new virtual private cloud;
identify routes in the multi-cloud environment based on one or more paths computed based on the topology information, wherein the one or more paths are between at least one of the private network, the one or more virtual private clouds, and the new virtual private cloud on the multi-cloud environment;
and
send, to the new virtual router, routing information for interconnecting the new virtual private cloud, the one or more virtual private clouds, and the private network in the multi-cloud environment, the routing information comprising the routes, segment routing identifiers and segment routing policies associated with the multi-cloud environment.

6 more elements

A non-transitory computer-readable storage medium comprising:

instructions stored therein instructions which, when executed by one or more processors, cause the one or more processors to:
add a new virtual private cloud to a multi-cloud environment comprising a private network associated with a cloud consumer and one or more virtual private clouds connected to the private network via a segment routing domain and respective virtual routers on the one or more virtual private clouds and the private network;
in response to adding the new virtual private cloud, deploy, on the new virtual private cloud, a new virtual router configured to route incoming and outgoing traffic for the new virtual private cloud;
receive, from the new virtual router, topology information associate with the new virtual private cloud;
identify routes in the multi-cloud environment based on one or more paths computed based on the topology information, wherein the one or more paths are between at least one of the private network, the one or more virtual private clouds, and the new virtual private cloud on the multi-cloud environment;
and
send, to the new virtual router, routing information for interconnecting the new virtual private cloud, the one or more virtual private clouds, and the private network in the multi-cloud environment, the routing information comprising the routes, segment routing identifiers and segment routing policies associated with the multi-cloud environment.
